About this 0.91ct natural emerald diamond

This 0.91ct natural emerald sits in the just-under-one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551238379. Listed at 6 retailers as of October 30, 2026, with prices from £630 to £1,163, a £532 spread on the same certified stone. With Clarity lists it at £1,163. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
